Description

Grinding device for polishing optical fiber preform Technical Field The utility model belongs to the technical field of optical fiber preforms, and particularly relates to a grinding device for polishing an optical fiber preform. Background Optical fiber preforms are the core material for manufacturing optical fibers, which is the first step in the fiber production process. An optical fiber preform is a special glass rod whose internal structure and composition determine the optical properties and quality of the final optical fiber. According to the disclosed rotary optical fiber perform magnetorheological polishing machine (publication number: CN 207255836U) comprises a magnetic rotating wheel, an electromagnet, a graphite rod, a tensioning wheel, a hollow main shaft, a bearing seat and a servo motor, wherein the servo motor drives the magnetic rotating wheel to rotate, the magnetic rotating wheel drives the electromagnet to rotate to form a high-speed rotating magnetic field, and the magnetic field acts on magnetorheological fluid in the quartz glass tube to form a high-speed rotating flexible polishing film. The utility model adopts different optical fiber perform clamping modes by utilizing a high-speed rotating magnetic field, and realizes polishing processing of the outer circle and the inner hole of the optical fiber perform immersed in the magnetorheological fluid loop. The rotating wheel, the electromagnet, the graphite rod, the tensioning wheel, the hollow main shaft and other components in the application are matched with each other to realize polishing processing of the outer circle and the inner hole of the optical fiber perform immersed in the magnetorheological fluid loop, but the problems that the height of a grinding machine and the position of the grinding machine cannot be adjusted in the grinding process of the optical fiber perform cannot be solved, and therefore, the grinding device for polishing the optical fiber perform is provided.
